Command Syntax

:CMODeN:UDEFined:BASe <amplitude>

<amplitude> is a double.

Where N identifies the common-mode waveform, which must be selected from {1:8}{A|C}. For example, the waveform of channels 1A and 2A would be identified as CMODe1A.

Query Syntax

:CMODeN:UDEFined:BASe?

Description

For the indicated common-mode waveform, sets or queries the custom base-level setting. The top and base levels are used to locate a waveform's lower, middle, and upper threshold levels during measurements. Specify the level in volts. Use :CMODe{1:4}:UDEFined:TOP to set or query a custom top level.

Before this custom base level can be applied to measurements, use the :MEASure:TBASe:METHod command to select custom top-base definitions.
